METHOD AND DEVICE FOR MANUFACTURING HELMET MAIN BODY

摘要

PURPOSE: A helmet main body manufacturing device and a method thereof are provided to continuously mold helmet main bodies without any curing time delay and densify the structure with uniform thickness and high strength by filling liquid state resin into micro holes of a stacking element. CONSTITUTION: A helmet main body manufacturing method includes the steps of forming stacking elements(100) in molds(2) in the shape of helmet main body separatively, injecting a liquid state thermoplastic resin(200) diluted with a curing agent into the molds and assembling a cover(6) mounted with an air bag(8) and a valve(32) for opening or closing the air bag for the injection of compression air, adhering the resin with the stacking element by pressing the liquid state resin by expanding the air bag by injecting the compressing air after connecting the valve with an air hose connecting element(34) connected to a compressor(12), and curing the resin in a curing room after closing the valve and separating the compressor from the molds.
